Description

Technical Field

[0001] The utility model relates to the technical field of plastic lunch box stacking equipment, in particular to a stacking device for processing plastic lunch boxes. Background Art

[0002] Plastic lunch boxes are plastic containers made of food-grade plastic raw materials for the convenience of taking out food. After the production and processing of plastic lunch boxes are completed, stacking devices are usually used to place and transport them.

[0003] The existing announcement number is CN217100093U, and its name is a stacking device for processing plastic lunch boxes, comprising an auxiliary mechanism, a stacking device body and a reinforcement mechanism. The stacking device body is arranged on the top of the auxiliary mechanism, and the outer side of the stacking device body is arranged with a reinforcement mechanism. The reinforcement mechanism comprises an outer cover, and a rotating shaft with one end penetrating and extending into the inner part of the outer cover is movably installed on the left side of the outer cover, a rotating rod is fixedly installed on the left side of the rotating shaft, and a driving gear is fixedly installed on the right side of the rotating shaft. By arranging a rotating rod, a driving gear and a driven gear in the reinforcement mechanism, the driving gear can be driven to rotate through the rotating shaft by holding the rotating rod and rotating it, and then the movable rod can be driven to rotate through the driven gear under the action of meshing, and because a limiting hole is provided, when the threaded rod is in the process of rotation, the position of the threaded block can be limited so that it drives the clamping plate to rise and fall, thereby facilitating the clamping and fixing of the plastic lunch box on the stacking device body.

[0004] However, the vertically stacked plastic lunch boxes are placed in the stacking device body, and the stacked plastic lunch boxes are squeezed and clamped in the stacking device body by using a liftable clamping plate. However, the clamping plate moves downward to squeeze and clamp the stacked plastic lunch boxes, which can only prevent the stacked plastic lunch boxes from overflowing the stacking device body, but cannot ensure that the stacked plastic lunch boxes are stacked crookedly, affecting the integrity of the stacked plastic lunch boxes.

A slide plate 12 is horizontally fixed on the support frame 11, and a sliding column 13 is vertically slidably installed on the slide plate 12, and the top end of the sliding column 13 is fixed to the bottom surface of the support frame 21. A support spring 14 is vertically sleeved on the sliding column 13, and the two ends of the support spring 14 are respectively fixed to the support frame 11 and the sliding column 13. The top of the support frame 11 is vertically fixed with a damping rod 15 on the top surface of the support frame 11, and the top of the damping rod 15 is fixed to the bottom surface of the support frame 21. During use, the formed plastic lunch boxes are inserted into the stacking basket 22 in sequence, and then the screw cover 241 on the pressing member 24 is assembled in the stacking basket 22, and multiple plastic lunch boxes are squeezed and clamped in the stacking basket 22. During transportation, the support frame 21 moves on the support frame 11, and the sliding column 13 is squeezed to slide vertically on the slide plate 12 of the support frame 11, squeezing the support spring 14 to deform and the damping rod 15 to stretch.

The positioning rod 18 is released and supported by the deformation force of the positioning spring 181, and the positioning rod 18 is pushed to insert into the positioning hole of the orifice plate 16, thereby ensuring the sliding length of the sliding frame 17 on the orifice plate 16.

[0025] Working principle: During use, the formed plastic lunch boxes are inserted into the stacking basket 22 one by one, and then the screw cover 241 on the pressing piece 24 is assembled in the stacking basket 22, and multiple plastic lunch boxes are squeezed and clamped in the stacking basket 22. During transportation, the support frame 21 moves on the supporting frame 11, and the squeezing slide column 13 slides vertically on the slide plate 12 of the supporting frame 11, squeezing the support spring 14 to deform and the damping rod 15 to stretch, and the vibration generated by the movement is filtered and removed by the deformation force of the spring 14, and then the deformation potential energy of the spring 14 is offset by the stretching of the damping rod 15, thereby ensuring that the pressing piece 24 presses down multiple plastic lunch boxes in the stacking basket 22.
